C8051F301-GMR

Overview

The C8051F301-GMR is a mixed-signal ISP Flash microcontroller from Silicon Labs, part of the C8051F30x family. It features an 8-bit CIP-51 core operating at up to 25 MHz with 25 MIPS throughput. The device includes 8 kB of in-system programmable Flash memory and 256 bytes of internal data RAM. Key peripherals include a hardware-enhanced UART, SMBus interface, three 16-bit counter/timers, and a Programmable Counter Array (PCA). It operates on a supply voltage of 2.7 V to 3.6 V and is available in an 11-pin QFN or 14-pin SOIC package.

Feature Summary

• Integrated on-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators.
• Pipelined instruction architecture that executes approximately 70% of instructions in one or two system clocks for high throughput.
• Programmable digital I/O and crossbar design allowing flexible mapping of internal digital resources to physical pins via software configuration.
• Supports on-the-fly switching between internal and external clock sources to facilitate power-saving modes.

Applications

• Infrared remote control systems
• Consumer electronics controllers
• Industrial process control devices
• Motor control applications

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific environmental certifications required by your region. Ensure the ordering suffix matches the desired package type and temperature range. Review the latest Product Change Notification (PCN) documents for any updates regarding assembly sites or material changes before finalizing procurement orders.

Selection Notes

Select this component when a fully integrated mixed-signal solution with on-chip debug capabilities is required. It is suitable for designs needing moderate Flash memory and standard serial communication interfaces. Consider alternative models within the F30x family if higher ADC resolution or additional analog peripherals are necessary. Evaluate pin count requirements carefully as the 11-pin QFN offers limited I/O compared to other packages.

Part Context

This microcontroller belongs to the C8051F30x series of mixed-signal ISP Flash MCUs. The family shares a common CIP-51 core architecture but varies in memory size and peripheral configurations. The C8051F301 specifically provides 8 kB of Flash and lacks the 8-bit ADC found in the C8051F300/2 variants. It is designed for cost-sensitive applications requiring high integration and low power consumption.

Replacement Considerations

Check for updated revisions within the C8051F30x family. Verify compatibility with existing development tools such as Simplicity Studio. Ensure pinout compatibility if replacing in an existing PCB layout. Consult official documentation for any functional differences between legacy and current production versions.
